What is known from tlie .sj)oeie.s of plants in the Clay of Tegelen, 

 points even to a somewhat warmer climate than that indicated by 

 the flora of the Cromer Bed, and so, seemingly, to a somewhat older 

 age. The Pninuo'-iipeties is certainly different from P. splnosa L., 

 which belongs to the Cromer fossil flora, and which is now also 

 indigenous in nortliern Europe. The seed is only assimilable with 

 that of species, which now appear to be spontaneous in Turkey, 

 south of the Caucasus, in /Vrmenia and northern Persia. Amongst the 

 plants of the Cromer Bed Vitis viiü/era is also wanting, whicli grows 

 now spontaneously in temperate West-Asia, especially in Armenia 

 and south of the Caucasus and the Caspian Sea, also in southern 

 Europe, Algeria and Marocco. Remains are also found in Pleistocene 

 travertines of Tuscany and southern France, whei-e the species, with 

 Ficus carlca L., is considered to be a renmant of the TertiaiT flora, 

 further in Italian lake-dwellings. Amongst the Jiumerous species of 

 plants of the Cromer Bed is wanting too Staphijlea }nnnatn. In wild 

 state this species does not grow now more northerly than southern 

 Germany, it is especially indignous in the Pontine countriets and 

 also in x'Vsia Minor. No species of Jiujlans has been found in the 

 Cromer Bed, JiKjlaus tephrodcs, the nut of which, like that of some 

 nearly related forms, is hardly discernable from the i)resent American 

 Juglans cinerea L., is a Tertiary species of Italia and tl)e middle of 

 Germany. The seed of tlie Stratiote.^ is very different from that of 

 aS'. ahides, on the contrary strikingly similar to that of »S'. Websteri 

 from the Upper Miocene of the Wetterau. In the Cromer Bed as yet no 

 Viburmun was found. The seed of the species from the Clay of 

 Tegelen closely resembles that of I". Opulm L., it is only larger 

 and a little less flat. The circumstance, that the genus Viburnum 

 played an important role among the Tertiary flora seems to me not 

 to be without bearing, in connexion with the above mentioned facts. 

 A similar consideration applies to the genus Conius, of which 

 another species, C mnyuinea L. is found in fossil state on the coast 

 of Norfolk. C. mas appears to grow, besides in Asia, only in southern 

 and central Europe. C. sangulnea, on the other hand is also indige- 

 nous in northern Europe. 



It wants no demonstration that the flora from the Travertines of 

 Taubach, to which, on conclusive grounds, the same age as that of 

 the Sands of Moosbach is no\v attributed, is a much younger one 

 than that of the Clay of Tegelen. The former contains arctic and 

 alpine forms, which are wanting here, on the other hand the fossil 

 flora of Taul)ach lacks the mentioned Tertiary forms and those 

 pointing to a warmer climate. From the fact that the flora of Tegelen
